In the first case ([fig. 70]) the iron is in two parts, which theoretically would allow of weakness, but in practice the basket answers its purpose well.
In [fig. 71] the rigid ironwork is placed by a wire rope spliced to make a complete circle. This kind of basket is easier to make and less in weight than those just mentioned, but the cost of the rope keeps the price high.
[Fig. 72] shows another safety arrangement. A is a tarred hemp rope built into the basket as shown, and the ends fitted with eyelets for hoisting purposes, the handles being kept for use by the workmen.
The arrangement is a practical one, and gives the required element of safety to the baskets so long as the rope remains sound.
Ordinarily constructed baskets can be made temporarily safe by passing the slinging rope or chain through the handles and round the bottom of the basket, as shown on [fig. 73]. To prevent the rope slipping, and to give the basket a flat bottom, pieces of wood can be fitted as shown.
Navvy Barrows.—Navvy barrows ([fig. 74]) are of hard wood, wrought and cast iron fittings and steel axles. They are fitted with iron, or wooden wheels bound with iron, and vary in weight from 60 to 75 lbs., and have a capacity of about 1⁄10 of a cubic yard.
